Enhancing the Performance of Wireless Mesh Network (WMN) for Video Traffic Transmission in Context with IEEE 802.11

Abstract

In recent years, multimedia streaming has increased dramatically in wireless networks. Applications such as Video-on-Demand (VoD) and distributed file backup appear in wireless mesh networks (WMNs). These applications have strict requirements for quality of service (QoS) with bandwidth guarantees. Streaming video flows over WMN faces some challenges as bandwidth guarantee; High data rate flows over a shared medium in a multihop manner can increase the packet loss and delay significantly. Real-time live surveillance applications do not usually use retransmission error control, video contents can be lost, and the quality of the video can be altered. This paper discussed methodology of video transmission ways in WMN which aggregates bandwidths, increase delivery ratio and decrease end-to-end delay, which determine the quality of the delivered video, high quality multimedia deliveries over wireless mesh networks. And throughput of this methodologies & further improvement of its performance.
